There are many types of firewall security solutions offered, many popular types of firewalls include application level, packet filtering, stateful firewalls, appliance-based network firewall for enterprise-level network security and simple software firewalls such as the Windows Firewall that is built into modern Microsoft Operating Systems.

Some of the most popular vendors of firewall technologies and solutions include Check Point, Barracuda and Cisco. Check Point distributes both personal and network level firewall products. Check Point is the creator of Zone Alarm which is a very simple and affordable solution for home PC users as it only costs around $40 a year for two licenses. Check Point also has enterprise firewall solutions such as the 61000 security system which can support 1 Terabyte of firewall throughput and 600,000 sessions per second which puts it in a league of its own. Cisco has hardware based firewall solutions such as their IOS and ASA security solutions. Barracuda offers a next generation firewall solution such as the NG model which provides VPN, NAC, Traffic Management and IPS services all rolled into one.

The obvious disadvantages to the network based higher level hardware firewalls is that they can be extremely expensive, such as the Barracuda NG F900 which retails for around $50,000. This makes it very hard for small businesses to have state of the art security technologies.

For home users and small businesses concerned about having a good firewall solution I would recommend a virtually free solution, install Linux on a PC or server and utilize IPTABLES and proxy software which is completely free and run your network behind it. For enterprise solutions the Barracuda NG F900 is top of the line as far as I’m concerned and you can’t go wrong with such a solution.
